Definition 2
A collection of conditions joined together via composition (ANDed) and/or optionality (ORed) to form a logical expression upon which the execution of an activity is based or upon which the cessation of a repeated activity is based, where components of the group may include other activities, observation results and/or other criterion groups, and where both the criterion group and its components are planned to be used at a particular point in a particular study. EXAMPLE(S): (A and (B or C)), where A might be an activity, B and C might be 2 different observation results, and the two sets of parentheses are 2 criterion groups, one inside (a component of) the other. NOTE(S): A criterion group represents the parentheses around a set of criteria in a logical expression. (NCI Thesaurus/BRIDG)
